详细说明： 类Ext.chart.BarChart 包： Extchart 定义的文件： Chart.js 类全称： Ext.chart.BarChart 继承自于： Ext.chart.CartesianChart 配置项配置项 定义者 x : Number 如果该组件是在一个定位的组件之中，可通过该属性返回组件的x本地（左边）... 如果该组件是在一个定位的组件之中，可通过该属性返回组件的x本地（左边）坐标。The local x (left) coordinate for this component if contained within a positioning container. BoxComponent y : Number 如果该组件是在一个定位的组件之中，可通过该属性返回组件的y本地（顶部）... 如果该组件是在一个定位的组件之中，可通过该属性返回组件的y本地（顶部）坐标。The local y (top) coordinate for this component if contained within a positioning container. BoxComponent pageX : Number 如果该组件是在一个定位的组件之中，可通过该属性返回组件的x页面坐标。T... 如果该组件是在一个定位的组件之中，可通过该属性返回组件的x页面坐标。The page level x coordinate for this component if contained within a positioning container. BoxComponent pageY : Number 如果该组件是在一个定位的组件之中，可通过该属性返回组件的y页面坐标。T... 如果该组件是在一个定位的组件之中，可通过该属性返回组件的y页面坐标。The page level y coordinate for this component if contained within a positioning container. BoxComponent height : Number 此组件的高度（单位象素）（缺省为auto）。The height of... 此组件的高度（单位象素）（缺省为auto）。The height of this component in pixels (defaults to auto). BoxComponent width : Number 此组件的宽度（单位象素）（缺省为auto）。The width of ... 此组件的宽度（单位象素）（缺省为auto）。The width of this component in pixels (defaults to auto). BoxComponent autoHeight : Boolean True表示为使用height:'auto'，false表示为使用固定... True表示为使用height:'auto'，false表示为使用固定高度（缺省为false）。注意：尽管许多组件都会继承该配置选项，但是不是全部的'auto' height都有效。autoHeight:true的设定表示会依照元素内容自适应大小，Ext就不会过问高度的问题。True to use height:'auto', false to use fixed height (defaults to false). Note: Although many components inherit this config option, not all will function as expected with a height of 'auto'. Setting autoHeight:true means that the browser will manage height based on the element's contents, and that Ext will not manage it at all. BoxComponent autoWidth : Boolean True表示为使用width:'auto'，false表示为使用固定宽... True表示为使用width:'auto'，false表示为使用固定宽度（缺省为false）。注意：尽管许多组件都会继承该配置选项，但是不是全部的'auto' width都有效。autoWidth:true的设定表示会依照元素内容自适应大小，Ext就不会过问宽度的问题。True to use width:'auto', false to use fixed width (defaults to false). Note: Although many components inherit this config option, not all will function as expected with a width of 'auto'. Setting autoWidth:true means that the browser will manage width based on the element's contents, and that Ext will not manage it at all. BoxComponent fieldLabel : String 在组件旁边那里显示的label文本（默认为''）。The label ... 在组件旁边那里显示的label文本（默认为''）。The label text to display next to this Component (defaults to '') 此组件只有在FormLayout布局管理器控制的容器下渲染才有用。This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: Component labelStyle : String 关于表单字段的label提示文本的CSS样式的“完全表达式（CSS s... 关于表单字段的label提示文本的CSS样式的“完全表达式（CSS style specification）”。默认为""，若容器的lableStyle有设置这样设置值。A CSS style specification to apply directly to this field's label (defaults to the container's labelStyle value if set, or ''). 此组件只有在FormLayout布局管理器控制的容器下渲染才有用。This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. 演示实例：Example use: Component labelSeparator : String 分隔符，就是每行表单中的label文本显示后面紧接着的那个分隔符（默认... 分隔符，就是每行表单中的label文本显示后面紧接着的那个分隔符（默认值是Ext.layout.FormLayoutlabelSeparator，即缺省是分号“:”）。如果指定空白字符串""就表示不显示所谓的“分隔符”。The standard separator to display after the text of each form label (defaults to the value of Ext.layout.FormLayoutlabelSeparator, which is a colon ':' by default). To display no separator for this field's label specify empty string ''. 此组件只有在FormLayout布局管理器控制的容器下渲染才有用。This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: Component hideLabel : Boolean True表示为完全隐藏label元素。默认下，即使你不指定fieldL... True表示为完全隐藏label元素。默认下，即使你不指定fieldLabel都会有一个空白符插入，好让支撑field为一行。设该值为true就不会有这个空白符了。True to completely hide the label element (defaults to false). By default, even if you do not specify a fieldLabel the space will still be reserved so that the field will line up with other fields that do have labels. Setting this to true will cause the field to not reserve that space. 此组件只有在FormLayout布局管理器控制的容器下渲染才有用。This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: Component clearCls : String 关于field的清除样式（默认为“x-form-clear-left”... 关于field的清除样式（默认为“x-form-clear-left”）。The CSS class used to provide field clearing (defaults to 'x-form-clear-left'). 此组件只有在FormLayout布局管理器控制的容器下渲染才有用。This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Component itemCls : String 关于容器的表单项元素的额外的CSS样式（默认为""，如容器的itemC... 关于容器的表单项元素的额外的CSS样式（默认为""，如容器的itemCls有设置的话就用那个值）。由于该样式是作用于整个条目容器的，这就会对在内的表单字段、label元素（若有指定）或其他元素只要属于条目内的元素都有效。An additional CSS class to apply to the wrapper's form item element of this field (defaults to the container's itemCls value if set, or ''). Since it is applied to the item wrapper, it allows you to write standard CSS rules that can apply to the field, the label (if specified) or any other element within the markup for the field. 此组件只有在FormLayout布局管理器控制的容器下渲染才有用。This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: Component anchor : String Note: this config is only used when... Note: this config is only used when this Component is rendered by a Container which has been configured to use an AnchorLayout based layout manager, for example: Ext.form.FormPanel specifying layout: 'anchor' // or 'form', or 'absolute' See Ext.layout.AnchorLayout.anchor also. Component id : String 唯一的组件id（默认为自动分配的id）。出于你打算用id来获取组件引用... 唯一的组件id（默认为自动分配的id）。出于你打算用id来获取组件引用这一目的（像使用Ext.ComponentMgrgetCmp的情形），你就会送入一个你写好的id到这个方法。提示：容器的元素即HTML元素也会使用该id渲染在页面上。如此一来你就可以采用CSS id匹配的规则来定义该组件的样式。换句话说，实例化该组件时，送入不同的Id，就有对应不同的样式效果。The unique id of this component (defaults to an auto-assigned id). You should assign an id if you need to be able to access the component later and you do not have an object reference available (e.g., using Ext.ComponentMgrgetCmp). Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent. Component itemId : String 若没有为该组件分配到一个访问的应用（换言之是建立变量然后分配置），那... 若没有为该组件分配到一个访问的应用（换言之是建立变量然后分配置），那么就可以用这个itemId的索引来获取这个组件， 另外一个方式就是id，对应用Ext.getCmp获取； 而itemId就对应用getComponent方法获取， 但范围更窄，在Ext.Container范围内。An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with Ext.getCmp, use itemId with Ext.Container. getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container -- avoiding potential conflicts with Ext.ComponentMgr which requires a unique id. Component xtype : String 用于登记一个xtype。The registered xtype to... 用于登记一个xtype。The registered xtype to create. This config option is not used when passing a config object into a constructor. This config option is used only when lazy instantiation is being used, and a child item of a Container is being specified not as a fully instantiated Component, but as a Component config object. The xtype will be looked up at render time up to determine what type of child Component to create. The predefined xtypes are listed here. If you subclass Components to create your own Components, you may register them using Ext.ComponentMgrregisterType in order to be able to take advantage of lazy instantiation and rendering. Component ptype : String The registered ptype to create. Thi... The registered ptype to create. This config option is not used when passing a config object into a constructor. This config option is used only when lazy instantiation is being used, and a Plugin is being specified not as a fully instantiated Component, but as a Component config object. The ptype will be looked up at render time up to determine what type of Plugin to create. If you create your own Plugins, you may register them using Ext.ComponentMgrregisterPlugin in order to be able to take advantage of lazy instantiation and rendering. Component cls : String 一个可选添加的CSS样式类，加入到组件的元素上（默认为''）。这为组件... 一个可选添加的CSS样式类，加入到组件的元素上（默认为''）。这为组件或组件的子节点加入标准CSS规则提供了方便。An optional extra CSS class that will be added to this component's Element (defaults to ''). This can be useful for adding customized styles to the component or any of its children using standard CSS rules. Component overCls : String 关于鼠标上移至该组件元素的CSS样式类，移出时撤销该样式的效果（默认为... 关于鼠标上移至该组件元素的CSS样式类，移出时撤销该样式的效果（默认为''）。该配置项在处理元素"active"或"hover"的时候很有用。An optional extra CSS class that will be added to this component's Element when the mouse moves over the Element, and removed when the mouse moves out. (defaults to ''). This can be useful for adding customized "active" or "hover" styles to the component or any of its children using standard CSS rules. Component style : String 作用在组件元素上特定的样式。该值的有效格式应如Ext.Elementa... 作用在组件元素上特定的样式。该值的有效格式应如Ext.ElementapplyStyles。A custom style specification to be applied to this component's Element. Should be a valid argument to Ext.ElementapplyStyles. Component ctCls : String 一个可选添加的CSS样式类，加入到组件的容器上（默认为''）。这为容器... 一个可选添加的CSS样式类，加入到组件的容器上（默认为''）。这为容器或容器的子节点加入标准CSS规则提供了方便。An optional extra CSS class that will be added to this component's container (defaults to ''). This can be useful for adding customized styles to the container or any of its children using standard CSS rules. Component ...展开收缩
